How we work

A clear four-step process, from first call to finished floor

Every Ottawa project moves through the same four steps. You always know what comes next, what it costs, and who is on site.

  1. Free in-home consultation

    We come to your Ottawa home, measure, listen, and flag the constraints (egress, ceiling height, lot slope) most homeowners miss. No obligation, no pressure.

  2. Feasibility & itemized quote

    You get a written, line-by-line quote, a real cost range, and a clear yes/no on whether your basement qualifies as a legal suite, in-law, or income space.

  3. Scope & fixed schedule

    We confirm the scope, sequence the work, and give you a single project manager from first site visit to final walkthrough.

  4. Build & walkthrough

    The crew builds to the agreed scope, keeps the site moving, and walks the finished basement with you before closeout.

Finishing

Turn the basement you store junk in into the floor you actually live on

A finished basement is the cheapest square footage you’ll ever add: a family room, a home office, a guest suite, all under your existing roof. We frame, insulate, wire, and finish to code, then hand you a space that feels like the rest of the house, not a renovated cellar.

And you’ll understand the number before we start: a finished basement in Ottawa typically runs C$45,000-C$95,000, then gets quoted line by line against your actual scope.

  • Finished layout, lighting, storage, and bathroom scope planned together
  • Budget drivers explained before you commit
  • A build sequence that keeps decisions organized

Legal suites & SDUs

Make the basement pay for itself

A legal secondary dwelling unit turns unused space into real monthly income, and adds value a finished rec room can’t. We handle the part most homeowners dread: egress windows, fire separation, ceiling height, separate entrance, and the City of Ottawa permits that make it legal rather than just rentable.

The value is in solving the constraints early: layout, ceiling height, egress, fire separation, separate entrance options, and the finished plan that a renter or family member can actually live in.

  • Egress, fire-separation, and ceiling-height brought to code
  • Suite feasibility reviewed before the quote is finalized
  • Walkout and separate-entrance options where the lot allows

What Ottawa homeowners ask

Common Basement Renovation Priorities

The same priorities come up across Ottawa basement projects: clear pricing, code-aware planning, and a crew that can take the work from first visit to final walkthrough.

Priority Suite planning
Homeowners planning a legal suite need the number in writing before they commit. The useful quote is itemized, tied to the actual scope, and clear about egress, fire separation, ceiling height, and inspection requirements.
Pricing clarity Barrhaven

Legal basement suite

Priority Emergency work
Flood work needs a phone-first path. Extraction, structural drying, moisture testing, mold-safe reconstruction, and a prevention fix all have to be handled in order, with no handoff halfway through.
Flood response Orléans

Flood rebuild & SDU

Priority Family space
A finished basement should feel like the rest of the house. That means code-correct framing, insulation, electrical, ventilation, flooring, trim, and a schedule that is explained before work starts.

FAQ

Basement Renovation in Ottawa: Quick Answers

Do you give useful price guidance before a site visit?
Yes. We start with realistic planning ranges and then turn your scope into an itemized quote before you commit. A finished basement typically runs C$45,000-C$95,000, and we’ll show you line by line where the budget goes.
How do you handle code and feasibility questions?
We flag the constraints that usually change the scope: ceiling height, egress, drainage, electrical, bedrooms, bathrooms, and suite requirements. If the project needs a deeper review, we explain that early instead of burying it in the quote.
Can you handle a flood from start to finish?
Yes. We prioritize flood requests, then take you through drying, mold-safe cleanup, reconstruction, and the waterproofing or backwater-valve planning needed to reduce the chance of repeat damage.
Which areas of Ottawa do you serve?
All of Ottawa, with dedicated local crews in Kanata, Barrhaven, Orléans, Nepean, Gloucester, Stittsville, and Manotick. Orléans is served bilingually (FR/EN).
How long does a typical basement renovation take?
A standard basement finishing project often runs 6-10 weeks after the scope is finalized. A legal suite, which adds egress, separate entrance, and fire separation, usually runs 10-16 weeks. You receive a schedule with your itemized quote.
Do you offer financing or help with flood rebates?
We do not arrange financing directly, but we’ll connect you with Ottawa’s protective-plumbing rebate program and the City’s compassionate flood grant, and we handle all the documentation and inspections those programs require.
